IBC (2006) addresses water supply valves... 903.3.5 Water supplies. Water supplies for automatic sprinkler systems shall comply with this section and the standards referenced in Section 903.3.1. The potable water supply shall be protected against backflow in accordance with the requirements of this section and the International Plumbing Code. [F]
903.4 Sprinkler system monitoring and alarms. [F] All valves controlling the water supply for automatic sprinkler systems, pumps, tanks, water levels and temperatures, critical air pressures and water-flow switches on all sprinkler systems shall be electrically supervised. Exceptions: 1. Automatic sprinkler systems protecting one- and two-family dwellings. 2. Limited area systems serving fewer than 20 sprinklers. 3. Automatic sprinkler systems installed in accordance with NFPA 13R where a common supply main is used to supply both domestic water and the automatic sprinkler systems and a separate shutoff valve for the automatic sprinkler system is not provided. 4. Jockey pump control valves that are sealed or locked in the open position. 5. Control valves to commercial kitchen hoods, paint spray booths or dip tanks that are sealed or locked in the open position. 6. Valves controlling the fuel supply to fire pump engines that are sealed or locked in the open position. 7. Trim valves to pressure switches in dry, preaction and deluge sprinkler systems that are sealed or locked in the open position. 903.4.1 Signals. [F] Alarm, supervisory and trouble signals shall be distinctly different and automatically transmitted to an approved central station, remote supervising station or proprietary supervising station as defined in NFPA 72 or, when approved by the fire code official, shall sound an audible signal at a constantly attended location. Exceptions: 1. Underground key or hub valves in roadway boxes provided by the municipality or public utility are not required to be monitored. 2. Backflow prevention device test valves located in limited area sprinkler system supply piping shall be locked in the open position. In occupancies required to be equipped with a fire alarm system, the backflow preventer valves shall be electrically supervised by a tamper switch installed in accordance with NFPA 72 and separately annunciated. 903.3.5.1 Domestic services. Where the domestic service provides the water supply for the automatic sprinkler system, the supply shall be in accordance with this section.

We use a state adopted (Indiana) code that is based almost entirely on IBC/IFC 2006. We've been asked to tamper PIVs per IBC/IFC. Our site includes a large campus fire main loop and there is some discussion about whether or not all those valves require tampering. My contention is that the campus fire main is a private fire service main and is outside the scope of IBC and the chapter 9 requirement to tamper all valves, IFC chapter 5 seems to be the correct code to apply and refers almost exclusively to NFPA 24 for private fire service mains. NFPA allows locking and periodic checks rather than requiring electronic monitoring as IBC/IFC chapter 9 does. Is there any succinct way to show the campus loop is out of the scope of IBC, or is my reasoning incorrect? Mike Morey, CFPS, SET Planner Scheduler/Designer BMWC Constructors, Inc. 1740 W.
